Letters PatentNo.A 111,406, datedlanuary 31, 1871.

IMPROVEMENT IN COMBINED COFFEE-MILLS ANDAPPLE-PARERS lThe Schedule referred to in these Letters Patent and making part of the same.

and arrangement of the grinding; apparatus of the mill. Thisconsists of a metal wheel, a metal bar,

concave on one side, making a littlemore than a semicircle, within which the wheel revolves. The periphery of the wheel is cut into diamondshaped squares of uniform size, having two cutting# edges.

Themetal bar is also cut into similar squareson its concave surface.

This'concave bar, whichforms the opposite grinding-surfaceto the wheel is held by a .screw at its npper end, and on which it turns when moved by au adj usting ratch at its lower end. A

The wheel, xedupon a shaft, is placed with the concave bar between two metallic plates, which are secured to the foundation-board, and through which the shaft passes, and which serve as pivot-holes for it .to turn in.

The second part of my invention'relates tothe combination and attachment of the apple-parer, so as to be operated by the same revolving shaft as the coffee-grinder.

This shaft is extended through the foundation-- board suciently far'to allow a screw to be formed on -the projecting end.

the foundation-board, thisplate having two projections corresponding with holes in the frame to which it is keyed..

The frame sustains two shafts, one of which carries two wheels, one large and one small.

The larger one, at the end ofthe shaft, Vis geared with the screw-wheel ofthe fork-shaft.

The smaller one, near the middle of the shaft, is geared with a larger one, which operates the knife.i

`A spiral spring fixed to the shaft of this larger wheel, and to the frame, returns theknife'to its position after having described its curve around, the apple.

A metallic rod, to one end of which the knife is xed,"passes through this wheel near its circumference, and is made fast to it by a pivot near the middle, of the rod. This allows the knife to move up and down as the size of the apple varies, but is kept fpressed upon it by an adjusting spiral spring at the other end ofthe rod.

This spring works upon a standard xed to the shaft of the Wheel that moves the knife, and moves witILit.

-Descrption of theAccompang/ing Drawing.-

Figure 1 is a` perspective view of the combination, coIee-mill and apple-parer attached.

Figure 2 represents the grinding apparatus of the mill with the outer plate removed.

Figure-3 is the plate with projections secured to the tbundation-board, to which the frame is keyed.
